CARPET-SECURING DEVICE.

Application filed July 14, 1924, Serial No. 725,865.

To @ZZ whom 'it may concern: I

Be it known that I, SAMUEL D. BUTTER- woR'rH, a citizen of the United States, residing at Lansing, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Carpet-Securing Devices, of which the ioliow'- ing is a specification. This invention relates to a carpet securing device, and has for its object securing meansr for clamping carpet to the floor without the use of tacks or other securing devices. l l

In hotels and oiiice buildingscarpets are laid so as to cover the entire floor area, and it has been customary tovtack the carpet down by folding the outer edge under and accurately litting the carpet to the room. This is a tedious and exacting job, and necessitates the employment of rather careful workmen with the resulting high labor cost in laying the carpet. It is necessary to cut the carpet accurately and to exactly fit the carpet to the rooin. TWith my device,

however, there is considerable leeway allowed in cutting the carpet and my" securing device which eliminates the tacking of the carpet to the floor lessensi'the labor cost of laying the carpet considerably. l y

Another advantage of my securing device is that the carpet may be removed from the iloor as quickly as the same is laid. Vhen the carpets are tacked it is quite a ob to remove all the'tacks to take theJA carpet away to be cleaned. lVith my device, however, it is merely a few minutes job to releasethe carpet so that the same may be removed from the floor t0 be cleaned and may be se' cured again in place without entailing a riveting of the carpet to the room, as is necessary when the carpet is tacked. A tacked carpet needs to be stretched and {itted to the room-an operation which must be repeated again when the carpet is relaid after cleaning or renovating. l

In most hotel constructions the iloors are made of poured concrete. A nailing strip is usually moulded into the iloor by the building contractor, and this is quite a complicated ob. The Hoor must be poured to a level about one inch below the level ot the floor; the nailing strip is then laid about the edge of the room and a final layer of concrete is poured within the room inside of the nailing strips to bring the level of the floor up t0 the level of the nailing strip. lith my device, however, the door may be poured in one operation, thus eliminating this extra pouring after the nailing' strip is located. My construction eliminates the nailing strip, as the carpet is not tacked. Another advantage with my construction is that the baseboard is made lof two parts, one of which is built into the building by the contractor, and the other part of the baseboard, which is a clamping member, is supplied by the carpet contractor, and both parts of the baseboard cooperate together to form a final baseboard for the room, as the same are designed so as to tit together and eliminate anyriitting ory relocating by .the contractor of the baseboard after the carpet'is laid. v

In the drawings:

Fig. 1 is a vertical sectional view through thecorner of the room showing the base board and Hoor construction, showing how my clampingl strip lis secured in place.

Fig. 2 is a'view similar to Fig. l, but showing'the clamping strip before itis sprung into' place.

Fig. 3 is a sectional perspective view of a modiiied construction wherein a metal baseboard and clamping stripare used.

Fig. 4 is a vertical sectional view or' the construction as shown in Fig. 3 and showing the means "whereby the. clamping strip may be removed to releasejthe carpet when the same is to be removed.

In Figs. 1 and 2, I show a baseboard constructed of a fibrous material, such as wood.

YThis baseboard comprisesvthe Lipper strip a, which is anchored to the wall of the lower clamping strip Z); In most hotels the walls are formed ot a hollow lireproof tile designated c and the 'tiles adjacent the floor are provided with the iiurring d and the grounds c which are formed of strips of wood laidl horizontally and secured to the urring carried by the tireproof tile. The upper member of the baseboard a may be nailed to these grounds or wood strips, the nails passing therethrough and into the furring. This will space the base board from the iireproot tile so that thewall plaster f when rplastered to the tile will come flush with the back of the baseboard. This method of securing the baseboard to the wall is old, and my improvement resides in the clamping strip which is part of my new form of baseboard construction.

My baseboard which comprises the two members al and Z2 as described, is clearly shown in Figs. l and 2, wherein the upper portion a oi'i the baseboard is spaced from the floor g. Secured to the floor or moulded therein is a concave rib or `ridge L. Obviously this rib may be secured to the floor by soine other fastening means than that shown in the dra-wings. ln the drawings l show the lower edge ot the rib dove-tail so that the saine will be anchored in the concrete floor when the concrete is poured. rEhe lower edge or the upper baseboard part al is provided witha groove z' and the beveller1 corner edge j. The clamping strip b is provided with a groove ,7c and a tongue m, whichl when sprung into place, is adapted to tit the tongue and groove carried by the upper baseboard part a.

In laying the carpet a thick layer ot telt or other padding n is laid over the concrete l'loor and roughly lits the room and is cut se that the saine will not extend over the 'ridge or rib 7L in the iioor. The carpet o is now laid over this padding and is of greater dimensions than the padding so that the edge the carpet extends over the rib It carried by the floor. The lower edge ot the clamp ing strip Z) is provided with a groove p which is complementary to the rounded contour oic the rib or ridge 7L. As clearly shown in Fig. 2 this clamping strip is set on the carpet over the rib 7L.. A board g, three or four 'feet in length, has one edge resting on the tloor at a point removed 'from the wall and the other edge engaging the top outer edo'e or the clamping strip. The man who is laying the carpet can then place his 'toot on this board and by bearing his weight thereon may torce the clamping strip into place, the carpet giving sutliciently to allow the same to be sprung under the baseboard part a, whereupon the tongue and groove connection between the two parts of the baseboard cooperating with the rib fr., consequently anchoring the edge of the carpet and clamping the same to the iioor. As shown in Fig. l it may be seen how this carpet is turned and clamped between the rib and the concave or grooved portion ot the clamping strip, thereby preventing the carpet from slipping.

ln Figs. 3 and t l show the preferred *form of my construction in which the baseboard is formed of sheet metal. This baseboard is formed of two parts, a-l and h1, the upper part of the baseboard al is secured to the turring by nails or other fastening devices 7, as shown in Fig. Kl. This portion ot the baseboard is provided with a lower extension which terminates in the roll or rib t and the entire baseboard section is i'ormed in such a way as to provide a channel which faces towards the center ot the room. rlhe upper wall ot said channel is provided with a tongue u. which runs lengthwise to the baseboardsection. The clamping strip b1 is also formed of sheet metal and is substantially U-shaped in cross section; the top leg ot said clamping strip provided with a groove u1 adapted to engage the tongue u carried by the other baseboard section. The lower leg ot the clamping strip is termed with a groove t1 cooperating with the roll or rib t of the other baseboard section.

The padding a is laid on the floor the saine way as above described and the carpet 0 is laid over the padding and has a greater dimension than the padding so that the edge of the carpet will extend into the channel formed by the hist-mentioned baseboard seetion al. The clamping strip is sprung into place in the saine manner as is the wood clau'iping strip Z) shown in Figs. l and 2.

ln Fig. l l show a means whereby this clamping strip may be removed to release the carpet. l use the same plank Q but provide a block v which may be laid on t-he floor at a point removed Yfrom the wall so as to raise the tulcruin point of the plank y above the topedge or" the clamping strip. A pressure on this plank will cause the same to bea-r down on the clamping strip in the direction as shown by the arrow, the components of said torce exerting a downward pressure on the clamping member and a pressure tending to force the saine away 'from the stationary baseboard section al. @bviously this will further compress the carpet until the tongue and groove connection 'uy and al between the clamping strip b1 and the stationary baseboard section al may separate to allow the clamping strip to be slipped out and removed whereupon theY carpet may be bodily removed from the room.

lith such a sheet metal baseboard construction, the section al may be secured in place by the contractor and the roll t and the tongue a are permanently and denitely located. The carpet contractor may insert the other part of the baseboard, toi-wit: the clamping strip b1.

lith the use of this construction the carpet is quickly laid and is better secured to the floor. All tacks or fastening devices are eliminated, thus allowing the carpet to be removed at any time with very little labor. In addition it is unnecessary to accurately cut the carpet as there is sulicient space behind the clamping strip so as yto allow quite a variation in the size of the carpet.
